IMPROVEMENT IN SASH-CORD FASTENERS.

Specification forming part of Letters Patent No. 177,655, dated May23,1876; application filed March 27, 1876. I

To all whom it may concern:

Be it known that I, JOHN OLTZ, of Ithaca, Tompkins county, New York,have invented a Window Sash Cord Fastener lor Clutch, which I have setforth in the following specification, reference being had to the accompanying drawings.

My invention consists of a sheet-metal toothed clutch, designed to graspthe cord, with no knot in the'sash end of the cord. It conforms in shapeto the usual form of the excavations made in sashes-t'hat is, to therounded pit made by a bit or anger, and to the channel or groove aboveit. Both the elasticity of the sides of my clutch and the forcing thegroove from the top of the sash down to any convenient place in the edgeof the sash, where I it terminates in the usual enlarged rounded cavity;and bis my clutch or fastener, made of sheet metal, with arm-s or sidesI) and I)", having teeth 0 at the upper ends, and at least one set ofteeth, 01, toward the rounded portion of the clutch. These teeth are forthe purpose of penetrating the sash-cord e sufficiently to hold the cordfast without-a knot in the rounded cavity; but, if preferred, a knot canbe tied and lie in the rounded extremity. Yet my design is to use noknots, as they use up much cord, and are diflicult to adjust.

In Fig. 2 the side of my fastener is seen to have the teeth 0 on oneside to lap over the made in the sides of the fastener, though one issufficient for ordinary weights.

In Fig. 3 the end teeth 0 are seen more I clearly. The sides b b are, onthe inside edges, bent slightly inward, in order that they may be slidinto the cavity made in the sash, and this slight wedge shape aids in sodoing. These teeth 0 can be of any number, size, and shape; but to havethe outer ones long and the middle ones shorter, as seen in the figure,seems to me best. v

To put my clutch or fastener into the sash, the cord 6 is put in, asseen in Fig. l, and the bent or beveled edges are slid into the groove0/ and cavity, Fig. 1.

To take the fastener and cord out of the sash, draw on the cord, (seento the left in Fig. 1,) and this raises the end out of the groove. Beardown on this end and the rounded end f springs out of the sash. Thus itis easily put in and easily taken out.

The advantages and uses of my invention are apparent to those skilled inthe artto which it appertains.

I claim- The metallic clutch or fastener 12, with elastic spring sidesI) and b, and provided with teeth or projections 0 and d and curvedextremity f, in combination with the sash a, the same constructed andoperating substantially as and for the purpose set forth.

- JOHN OLTZ.
